It's looking less and less likely that Labor will succeed in pushing its internet filter plan through federal parliament with the Greens today showing their support alongside the Coalition in calling for a PC-based approach.

Greens ICT spokesman Scott Ludlam unveiled the party's cyber safety policy this morning which is all about PC-based filtering, further research into cyber safety risks, strengthened law enforcement and net literacy education.

"The Greens believe Australians need a world-class national broadband network but we don't need the Australian government looking over our shoulder and filtering what we see. A voluntary filter at the household level would be more effective to protect kids" said Senator Ludlam.

He then went on to say that there should be an obligation placed on all Australian ISPs to 'offer' PC based filtering solutions that can be customised to block a broad range of content and Police cyber crime units should also be better resourced.
